Why then the popular idea that a hard-boiled egg is “absolutely indigestible”? A hard-boiled egg, or more than one, eaten rapidly, without mastication, at a picnic, and with much sweet food at an unusual hour, may interfere with the “ease and comfort in digestion” resulting from such a meal. But if the whites of the hard-boiled eggs are chopped fine, the yolk mashed, and the two served upon toast, thus insuring mastication, a dish is produced that is of average digestibility and that may be used for breakfast or luncheon without hesitation.
If a tender, jellylike consistency is wanted, cook the egg below the boiling point of water. If, however, a firmer egg is preferred, use the old-time method, and cook the egg three or four minutes in boiling water. It is the easier and quicker method.
Moreover, do not hesitate to use an egg “boiled” half an hour, provided it is chopped fine or sliced.
GENERAL METHODS AND RECIPES
1. Eggs used raw.—An egg, swallowed whole, followed by a cracker, is a “quick lunch” that is not harmful, and it is sometimes convenient to be able to take an egg in this way. A sprinkling of salt upon it makes it more agreeable.
2. Beaten eggs.—Beat the yolk and white separately. Add to the yolk a teaspoonful of sugar, a shake of salt, some flavoring, and 3⁄4 of a cup of milk. Beat the white gently into this mixture and serve in a glass. The flavoring may be a quarter of a teaspoonful of vanilla, or a tablespoonful of orange juice. This is sometimes served to an invalid who can take milk, and is an agreeable luncheon for any one. If milk does not agree with one, a larger amount of fruit juice may be used with the addition of some water, possibly carbonated. The white
alone is given in cases of severe illness, mixed with a small amount of water, and fruit juice if the physician permits the latter. This is sometimes the only food that can be retained by an invalid.
Principles of egg cookery.—Protein in the form of an egg-albumin is the foodstuff to consider in the cooking of eggs. Heat produces in the egg a change in color and in texture or firmness, the firmness or hardness depending upon the degree of heat and the length of time given to the cooking. Coagulation is the term used for this change in the egg-albumin.
1. The white of egg begins to coagulate and to show an opaque white at about 180° F.
2. A temperature somewhat below the boiling point of water for about ten minutes will give the white a jellylike, tender consistency, and slightly cook the yolk. Continued for an hour, the white becomes solid and adheres to the shell.
